- LUBRICANT-MEASUREB.

Application filed December 10,1913.

To all whom it may concern Be it known that I, DAVID STANLEY Ham, acitizen of the United States, residing at Mer Rouge, in the parish ofMorehouse and State of Louisiana, have invented certain new and usefulImprovements in Lubricant- .Measurers, of which the following is aspecipositive in action, economical to construct and provided withindicating means which show the quantity of grease delivered in gallonunits, and fractional parts thereof or on any other basis' ofmeasurement.

'VVith these and related ends in view I show such adaptations in theaccompanying drawing.as will disclose the broad features of my inventionwithout limiting myself to the specific details shown.

Figure 1. shows a side elevation partly in section. Fig. 2. is anenlarged sectional elevation of the piston and its related valve partsFig. 3. is an elevation of the measuring dial. Fig. 4. shows the meansfor actuating the measuring hand. Fig. 5. is a plan view, disclosing themeans used to move the pistonnp and down within the container.

A large'container 1 is provided" with a cover 2 that may be suitablyhinged thereto and also locked if desired. The bottom 3 of the containeris conical.- The whole is sup ported by legs 4 which in turn are securedto a base platform 46 that is fastened to suitable wheel supports 42 and43. A handle 44 'is useful in moving the device from pltce to place.

A cylinder 6 is fastened to the conical part 3 by the flange 5. Itprojects upward into the container 1 and also depends below the same, soas to approximately form an extension thereof. At its upper end a cap 7is placed. It has a guide 8 and bearing '9 cast thereon. Suitable rivetsor other fastenings hold it in place.

10 is the operating shaft carrying -a pinion 11 which meshes into rack12 whose lower end is hollow and has a slot 14, flange l9 and threadedextension 20.

in the cylinder 6 so as to form free communication with the greasestored in conta ner 1 .so that as the piston 21 is being raised thegrease will flow through openings 13 into the space below'the piston,passing through apertures 22 and between the'annular space formed by thedisk 17 and packing ring 23 held on piston 21. The disk 17 is secured tostem 15 by nut 18. The stem is free to slide up and down in the lowerend of rack bar 12 and a pin 16 sliding in slot 14 prevents disk 17 fromrotating. The space below the piston fills with grease that is forcedout on its downward stroke through valve 25, nozzle 28 and delivery hose29. The valve 25 is held in a. raised position by spring 26. This springhas sulficient tension to withstand the weight of the grease above itand it serves to hold the valve closed until the piston has passed thelower end of openings 13 when it opens to allow the fixed quantity ofgrease to be delivered. A casing 27 forms a delivery space below thevalve and also serves as a seat for the spring 26. In order that thedelivery hose 29 may be kept from kinking, etc., as the device is movedfrom place to place a suitable hook 30 is secured to the side of the Thecylinder 6 is closed at its lower end by cap 24 which supports the valve25 and casing 27. It is reinforced by tie rods 31 which connect it tothe legs 4.

In order that the quantity of grease dclivered may be measured I place apinion 32 on shaft 10, exterior to the container 1. A gear 36 meshestherei ith and a pointer 37 is connected with the ear through a shortshaft This shaft is held and the gears incloscd by a casing 33, Thatportion 34 of the casingwhich covers gear 36 has formed thereonconcentric price lines 40 which are intersected by radial quantity lines39 and the pointer 37 has V shaped price leaders 38 which registerwiththe concentric price circles. A thumb screw.41 may be used ifdesired to adjustably secure the pointer 37 .to.

shaft 35. T he-sha ft 10 is rotated back and forth by handle 45. Theratio of gear 3610 pinion 32 is such that an entire revolution of thegear conforms to the entire stroke of piston 21. Approximately Q; of thecircumference of cover 34 is blank. This is the idle space pasmd over bythe pointer 37 during the movement of piston "21 throughout the lengthof slots 13 and the remaining} of the circumference corresponds to theactual permanently held by a delivery stroke of the piston. When thepointer is set at its proper place it may be suitable pin instead of setscrew 41.

If desired the price values may be formed on a removable plate securedto the pointer 37 so that the circles 40 may be 'made to serve forvarying values. In such cases the.

cover 34: would also have a removable plate held by screws 47 on whichthe radial lines 39 and circles {10 as well a the resultant prices forvarying quantities at difierent prices would be indicated so as'toconform-to the price values on the pointer or marked at the terminationof the concentric circles. In

order to facilitate the changing of plate 34- without removing thepointer 37 from the shaft 35 a slotof sufficient width to pass shaft 35may beformed in such plate, projecting radially from its center into theunoccupied s'pace, as shown by dotted lines 48 of Fig. 3. In this way.the device is easily changed from one -set of values or units ofmeasurement to others as desired. In order to make the unit spacebelowthe piston conform to the indications "on plate 34 the length of thepacking ring 23 may be changed as shown in Fig. 2 according to the basisof values or quantities that are to be used. The vacant space on plate-34 would obviously conform to such change.

The actionof'the device is as follows;

On the down stroke'o'f the piston all the iniprisoned grease isforcedout ahead of it but the lubricant also follows after the piston so thatthe moment it starts to rise thedisk 17 and stem 15 remain stationaryuntil slot 14 engages'pin 16,.whenthe disk ,17 is raised with thepiston, at which =time the grease flows between "17 and 23 into the funit space below the piston, continuing to do so fas long as the pistonis risin On the down stroke, the surplus material which has 'enteredcylinder 6 is forced out through openings 13, disk 17 remaining withinthe packing ring 23 so as to kep openings 22 closed.

' In case it should be desired to operate the measurer by power suitableaiitomatic reversing devices, of well known construction could be usedtocontrol the timing and the direction of movement-0f the piston.
